Stock exhaust system video

The Aventador's 6.5-liter V12 gets a distinct note courtesy of the Southern California dealership, which specializes in creating new exhausts for Lambos.

Lamborghini Newport Beach's bolt-on exhaust system is undergoing final testing before being released for sale.

The exhaust requires no reprogramming or heavy modifications. The dealership plans to test the part on the dyno at exotic and import-tuning shop SP Engineering in City of Industry, Calif., within the next two months.
